Vovlo Penta AQ170 water in oil.

Re: Vovlo Penta AQ170 water in oil.

If the bolts are still in good shape there's no reason to replace them. I'd use a little (!) compound to cope with minor scratches in the surfaces but just a thin line.<br /><br />Check my previous post regarding torques. I think it's important to clean and oil the threads as the torque setting must no be affected by dirt.<br /><br />Also remember that valve clearance should be as specified - better a little too distant than too close.<br /><br />Did you find any signs of leaking around the water pump?

No signs of leaking around the water pump UU. Head gasket arrived today and the head will be available tomorrow morning after a surface grind at the local machine shop.

Sounds good. Afterall you're on the way. Take your time and put the old lady back together with great care. <br /><br />Hopefully it all didn't cost you an arm and a leg?

BTW: Just browsed your site. How's that Commodore for towing?

You web page is like some kind of porn site, it kills with the pop-ups.<br />Anyways, early Volvo V6 motors were designed and built by Renault and you know how those French are, besides their vine and cheese they are good at nothing I know from my car repair days that V6 Volvos always had blown head gaskets.<br />You will need to machine shop these heads to make sure that they are not warp, because as I recall heads and the block are aluminum on this motor.

Sorry 'bout the pop-ups Mish_Mish but the site was my first effort and the free host has pop-ups. I will be moving it to another when time permits. Anyways, it's just another way for us to have a laugh at ourselves.<br /><br />UU the Commodore has an 1800kg towing kit fitted and the rig comes in at just under when loaded. She has plenty of power both going and stopping. I understand it will probably shorten the life of the car but when it is part of a salary package one tends to not give a stuff. How on earth did you pick it as a Commodore from the pic?<br />Costs were pretty good I thought, $125 for head gasket and $60 for head machining. Toss is a penny for oil, plugs and the like and it hits 'bout AU$220, which is close to US$3.50. (in reality abt US$100.) When doing labour myself it takes more time but is somehow very satisfying.<br />Will I need observe any kind of "running in" period?<br />I shall report back tomorrow when all is fitted.

Re: Vovlo Penta AQ170 water in oil.

The car is visible on one of the pics and a Holden Commodore is about the only one looking this way. So. Also, I had one for my Ozzy cruise (6000 km in 30 days), so I know what it's like. By the way, seems to be important to keep wheel alignment up to it's best to get a comfortable ride and handling.<br /><br />It is true that Volvo's V6 were made in coop with Renault and Peugeot/Citroën. But that was after the B30 which is straight 6 and, as mentioned, is a proplonged B20. The B27 is a V6 and was used in the 264. Not very good, one must admit, and not in use anymore by any of the parties.<br /><br />Running in is always to be considered. I'd take it easy and keep low rpm for a good while, watching it closely. Temperature, oil and weird sounds. Remember the recommended routine about head bolts fitting and torque.<br /><br />And forever after give it and extra oil check now and then.<br /><br />You seem to end up with a fair cost - which is good considering the 'ol thing may or may not have suffered in other parts.

When were you in Oz UU? I sure would like to hear more about your travels! I also would like to say thank you for all your help in getting this old girl up and ready again. I very much appreciate it. I picked up the head this afternoon and will fit it in the morning.

Re: Vovlo Penta AQ170 water in oil.

As the short version of my Oz travel resume is about one hour (and that's just for the latest trip), we better move the conversation out of this forum.<br /><br />Let me have your email. Leave it at never.send@mail.com and I'll reply asap.

All now back together but need to adjust valve clearances. Can anyone advise these specs please ?

Re: Vovlo Penta AQ170 water in oil.

Never find thanks. Found them @ volvoworld.com. 0.20 and 0.22.

Done. All together and running. Thanks to all for helping out.

Re: Vovlo Penta AQ170 water in oil.

I took her for her first run last week and she went well. Onboard was my neighbor, and auto mechanic. Upon returning and cleaning up I had a lood inside the rocker cover and as expected the oil was milky. My mate said that was to be expected as some water would still be in the motor. No worries. Yesterday I changed the oil and filter again and ran her on the flusher for 15- 20 mins and again the oil was milky. Is this acceptable on the 2nd oil change ? Would water still be in there ? Compression is fine and I did the seals on the sewater pump before reassembling her for good measure. Exhaust manifold is less than 12 months old so I hope that is not the prob. Any suggestions please ?
